Kinetin Reversal of NaCl Effects.
Leaf discs of Nicotiana rustica L. were floated on NaCl in the presence of kinetin or abscisic acid. On the 5th day (14)CO(2) fixation, [(3)H]leucine incorporation, stomatal conductance, and chlorophyll content were determined. Kinetin either partially or completely reversed the inhibitory effects of NaCl while ABA had no effect.
متن کاملReversal of induced dormancy in lettuce by ethylene, kinetin, and gibberellic Acid.
The germination of lettuce seeds (Lactuca sativa L., cv. Premier Great Lakes) was significantly inhibited by high temperature (32 C), 0.1 mM abscisic acid or 0.4 M mannitol. Ethylene (16 mul/1 of air) partially reversed the dormancy induced by all three inhibitors but only in the presence of 1 mM gibberellic acid (GA) or light. Neither ethylene plus GA nor ethylene plus light were able to promo...
متن کاملEffects of Kinetin on the Permeability of Allium cepa Cells.
Permeability changes of Allium cepa cells were studied by a plasmometric method. Onion epidermis was floated in phosphate buffer solution with kinetin (2.5 milligrams/liter), or buffer without kinetin as a control, for 10 hours. The treated and control tissues were then transferred to one of the following four permeants: thiourea, urea, maloamide, dimethylurea.Kinetin treatment increased the pe...
متن کاملKinetin & Kinetin Analogues as Substrates & Inhibitors of Xanthine Oxidase.
The discovery of the stimulation of cell division in plant tissues by trace amounts of kinetin, 6(2-furfuryl) aminopurine (11), has resulted in a number of investigations concerned with the effects of this and related compounds on a variety of plant and animal systems (4, 5, 7,9, 10, 12, 13). One system, developed for study of the in situ effect of agents upon the maintenance of normal organiza...
متن کاملAbscisic Acid-induced Changes in Nucleotide Composition of Rapidly Labeled Ribonucleic Acid Species of Lentil Root: Reversal by Kinetin.
An antagonism between cytokinins and growth inhibitors has been shown in germination (4, 5, 9, 12). Cytokinin-inhibitor antagonism has also been observed at the level of enzyme synthesis (6, 13). Based on a number of studies in which exogenous hormones were used to control germination, it has been hypothesized that in the regulation of germination, gibberellin is the primary stimulus and that t...
